PROCESS FOR PRINTING UPON TEXTILE FABRICS.

Application filed Kay 18, 1925, Serial No. 31,194; and in France June 16, 1924.

The process which is most frequently emwhich is to be printed. In the present inployed for the printing of textile fabrics in vention the absorbing belt A is represented roller printing machines consists in principle by a fine metallic gauze. This receives the in passing the'piece of material to be printed excess color from the printing rollers F between two rollers whereof one is a copper which traverses the fabric C. The said wire roller carrying designs on which the coloring gauze member receives the excess of the matter is disposed d th th r i aprescoloring matter-in the same manner as the sure roller which is usually of a larger size. known absorbing member-and it may be To obtain the proper results, it is necesfreed from this coloring matter by an arm Sary t wind upon the said pressure roller rangement of brushes, optionally followed several layers of a soft fabric, or lapping, by a washing device E, or like means. The d t employ an endless band of a felted said wire gauze member can be readily dried or bb covered 1 th by utilizing the heat of a drying drum F or In order to prevent the endless band from of the heating chamber. The major part of 15 being soiled to an improper degree due to the i s moisture can be expelled by suction an excess of colour, it has been found quite ing.

Having now particularly described my invention and the manner in which the same is to be performed, I declare that what I claim is:

1. In apparatus for printing textile fabrics, a pressure roller and an endless belt of metallic gauze between this pressure roller and the piece of fabric to be printed for absorbing the excess color.

2.'In apparatus for printing textile fabrics, a ressure roller, a lapping of elastic materia on said roller, and an endless band of metallic gauze between said lapping and the piece of fabric to be printed for absorbing excess color.

3. In apparatus for printing textile fabrice, a pressure means, and color supplying means and an endless belt of metallic gauze for absorbing excess color, travelling with the fabric to be colored between the pressure means and the color supplying means.

In testimony whereof I have signed my name to this specification.
